I'm sure being most of us like video games, we also like the music associated with them. Some have probably heard of it, this is a pretty popular video game music remixing site. All free for downloading, and it's not crap remixing either. You'd see from the front page that Capcom did a stint with these guys to have them remix music for a new Street Fighter Turbo HD game. Go take a listen if you haven't.
